FEATURES
DESCRIPTION
True hermetic sealing with metal-to-metal and glass-to-metal
design and manufacturing processes assures the Honeywell
MICRO SWITCH™ HE Series mechanical limit switches are
durable in severe environments. The hermetically sealed
HE Series limit switches are an effective solution for harsh
applications where the atmospheric pressures and temperatures
exhibit significant variations such as in commercial and military
aircraft. With a 300 series stainless steel bushing and housing,
the HE limit switch is able to resist most severe environments
with the environmental and hermetic sealing. Select HE Series
catalog listings are qualified to MIL-PRF-8805 standards.
HE Series limit switches are designed with either a 5/8 inch
or 15/32 inch diameter threaded bushing for panel mounted
applications.

HE SERIES SWITCHES
The HE Series hermetically sealed switches are designed with a threaded bushing
for panel mount applications. The standard
HE Series has a threaded bushing, 0.625
in [5/8 in] diameter. The miniature HE
Series and rotary actuated HE Series have
a threaded bushing that measures 0.469 in
[15/32 in] diameter.
HE Series switches generally feature electrical termination as side-exit or end-exit
wire leads, or terminal screws integral to
the switch. Military-style connectors, integral to the HE switch, are also available.

ELECTROMECHANICAL SWITCHES
Definitions below explain the meaning of
operating characteristics. Characteristics
shown in tables were chosen as most
significant. They are taken at normal room
temperature and humidity. These may vary
as temperature and humidity conditions differ. Sketches show how characteristics are
measured for in-line plunger actuation.
Linear dimensions for in-line actuation are
from top of plunger to a reference line, usually the center of the mounting holes.
Differential Travel (D.T.) – Plunger or
actuator travel from point where contacts
‘‘snap-over’’ to point where they ‘‘snapback.’’
Free Position (F.P.) – Position of switch
plunger or actuator when no external force
is applied (other than gravity).
Full Overtravel Force – Force required to
attain full overtravel of actuator.
Operating Position (O.P.) – Position of
switch plunger or actuator at which point
contacts snap from normal to operated
position. Note that in the case of flexible or
adjustable actuators, the operating position
is measured from the end of the lever or
its maximum length. Location of operating
position measurement shown on mounting
dimension drawings.
Operating Force (O.F.) – Amount of force
applied to switch plunger or actuator to
cause contact ‘‘snap-over.’’ Note in the case
of adjustable actuators, the force is measured from the maximum length position of
the lever.

Overtravel
Overtravel (O.T.) – Plunger or actuator
travel available beyond operating position.
Pretravel (P.T.) – Distance or angle traveled in moving plunger or actuator from
free position to operating position.
Release Force (R.F.) – Amount of force
still applied to switch plunger or actuator at
moment contacts snap from operated position to unoperated position.
Total Travel (T.T.) – Distance from actuator
free position to overtravel limit position.
